If you inherited a system that depends on this plugin, treat it as a temporary liability. Begin planning a migration to an HTML5-based recorder or a software VMS. If you are setting up a new system, avoid any NVR that still requires a browser plugin—the era of ActiveX in surveillance is over, and v3.05.26 is a ghost that should be laid to rest.
Keep a copy of the installer .exe and a Windows 10 LTSC VM snapshot. Because one day, Microsoft will finally remove IE completely, and on that day, many surveillance rooms will go blind. Have you encountered a specific issue with v3.05.26? Check the NVR’s firmware date—any device requiring this plugin is likely from 2016 or earlier.
